Can I get opa parameters inside rego ?

[vas-rus]

I want to run different commands based on different env , how I can pass env value to rego file (running in test or prod) , so that decision can be made at runtime ?

opa.runtime().env should have the env vars your server or command was started with. Try opa eval -fpretty 'opa.runtime()'.

But please be aware that this can make your policies harder to test: there's suddenly an environmental dependency that might not be obvious on the surface. But it's possible to overwrite opa.runtime() in tests, though, too.
